Reduced pressure therapy of the sacral region
View Patent ↗Reduced pressure wound therapy is performed on a sacral region of a patient using an adhesive dressing comprising a flexible planar layer and a non-planar fold-sealing region configured to seal to the intergluteal cleft of a patient. The fold-sealing region is located on an outer edge of the adhesive dressing and comprises a tapered configuration.
1. A device to treat a region of a patient having a skin fold, comprising:
a base layer comprising a first surface, a second surface, an interior region and an outer perimeter, and a non-planar sealing region located about the outer perimeter of the base layer;
tubing directly attached to the second surface of the base layer; and
an adhesive located on the base layer and on at least a portion of the sealing region.
2. The device of claim 1 , wherein the non-planar sealing region comprises a tapered region and a taper peak, wherein the tapered region has a taper length and a taper slope.
3. The device of claim 2 , wherein the non-planar sealing region comprises a plurality of tapered regions and taper peaks.
4. The device of claim 2 , wherein the tapered region comprises one or more elastic regions configured to change the taper slope when stretched.
5. The device of claim 2 , wherein the non-planar sealing region further comprises a cavity.
6. The device of claim 5 , wherein the non-planar sealing region further comprises a pushing element located in the cavity, wherein the pushing element is configured to push outwardly against the cavity.
7. The device of claim 6 , wherein the pushing element comprises a filament that is coupled to the taper peak and extends along the taper length.
8. The device of claim 6 , wherein the pushing element comprises a sack containing an expandable element.
9. The device of claim 8 , wherein the expandable element is a foam.
10. The device of claim 8 , wherein the expandable element is a fluid.
11. The device of claim 1 , wherein the non-planar sealing region is integrally formed with the base layer.
12. The device of claim 1 , wherein the non-planar sealing region is attached to the base layer at the point of manufacture.
13. The device of claim 1 , further comprising tubing located within the base layer.
14. The device of claim 1 , further comprising tubing directly attached to the first surface of the base layer.
15. The device of claim 1 , wherein the tubing is directly attached to both the first surface and the second surface of the base layer.
16. A device to treat a region of a patient having a skin fold, comprising:
a base layer comprising a first surface, a second surface, an interior region and an outer perimeter, and a non-planar sealing region located about the outer perimeter of the base layer; and
an adhesive located on the base layer and on at least a portion of the sealing region;
wherein the non-planar sealing region comprises:
a tapered region, wherein the tapered region has a taper length and a taper slope;
a taper peak;
a cavity; and
a pushing element located in the cavity and comprising a sack containing an expandable element, wherein the pushing element is configured to push outwardly against the cavity and wherein the expandable element is a fluid.
17. The device of claim 16 , wherein the non-planar sealing region comprises a plurality of tapered regions and taper peaks.
18. The device of claim 16 , wherein the tapered region comprises one or more elastic regions configured to change the taper slope when stretched.
19. The device of claim 16 , wherein the pushing element comprises a filament that is coupled to the taper peak and extends along the taper length.
20. The device of claim 16 , wherein the non-planar sealing region is integrally formed with the base layer.
21. The device of claim 16 , wherein the non-planar sealing region is attached to the base layer at the point of manufacture.
22. The device of claim 16 , further comprising tubing located within the base layer.
23. The device of claim 16 , further comprising tubing directly attached to the first surface of the base layer.
24. The device of claim 16 , further comprising tubing directly attached to the second surface of the base layer.
25. The device of claim 16 , further comprising tubing directly attached to both the first surface and the second surface of the base layer.
